How to install and delete ubuntu9.04 and Windows XP on a hard disk to completely delete win7 and remove the startup items of Windows 7 Installer (very simple)

Delete ubuntu9.04 from hard disk installation

I tried and tried on XP

It should also apply to win7, because the original author said it was under win7. (See below)

Vista has never been tried. It should be okay.

Prerequisites: There are both ubuntu8.04 and 9.04 ISO images.

All failed after multiple methods were tested on the Internet! Until you see this article: (Click + expand source to view)In Windows 7, wubi installs "new oxygen ubuntu9.04" in a traditional way that does not spread over the network! <Br/> first of all, I think it is necessary for me to introduce the wubi Method for installing ubuntu9.04, because too many people cannot solve this problem. <Br/> Please read the following text with patience, because this is the experience I learned after one night and one morning. It is absolutely valid and is not reproduced on the Internet! <Br/> yesterday, I saw a "new oxygen Ubuntu" from the new oxygen team, so I really wanted to try it, when I came back in the evening, I killed 8.04 of my systems for a long time. I thought it was easy to install this new oxygen ubuntu. However, there were so many twists and turns. My current system is Windows 7. It can be said that under this new system, whether many things can run perfectly must be proved by practice. Some previous methods for installing ubuntu9.04 were based on XP or Vista, but after my overnight + one morning verification, they were all ineffective! <Br/> I have tried the following methods on the Internet: <br/> 1. You can directly run the wubi9.04 package that comes with the image to install the hard disk, however, it turns out invalid! <Br/> 2. Modify the region language option to English. It is verified to be invalid! <Br/> 3. This is also the most widely used method, that is, to modify the temporary file of drive C and use the wubi8.10 installation method. The verification is invalid! <Br/> when the above methods are used, and I fail to succeed, what is the final installation method? Continue. <Br/> my method: <br/> the original Ubuntu installation image is saved in my system. It is feasible to use wubi to install it in Windows 7, (if it is ubuntu8.10, I think it is also possible), the following is the procedure. <Br/> Step 1: Run wubi8.04 to install ubuntu8.04. At this time, it will copy the files to be installed to the directory you want to install (I will not say much about the wubi operations, if not, Google). After wubi finishes all these preparations, it will prompt you to restart. Note that at this time, choose "restart yourself later". <Br/> Step 2: copy the ISO image file ubuntu9.04 you want to install to the "Install" folder in the Ubuntu installation directory, you will find that the ubuntu8.04 image exists in this directory. All you need to do is delete it and change the copied ubuntu9.04 image name to the name of ubuntu8.04. <Br/> Step 3: copy the initrd.gz and vmlinuz files in the ubuntu9.04image to a winboot folder (note: this folder may be used. I am using the latest and vmlinuz files. <Br/> after completing the above three steps, you can restart the computer. You will see the Dual Boot menu, select the Ubuntu option, and install it. <Br/> Note: If you are prompted to cancel the mounting during installation, click "continue installation" and the installation will be normal. In addition, the dual-Start Menu is automatically created after the installation, and the network setting is also very simple after the system is installed. I am a company bound to the physical address can be connected to the network, the operation is the same as that in windows. <Br/> okay. After the installation is complete, try ubuntu9.04 to surprise you! <Br/> [my installation information: new oxygen ubuntu9.04, amd4000 +, 3G memory, 7600gt graphics card]

After reading it, I felt the same way. At the same time, I had the ubuntu8.04 and 9.04 ISO files. After practice, I finally succeeded!

Note: The author says it is written by memory. The third step is indeed different from the actual situation. I opened a folder to find files with the same name as initrd.gz and vmlinuz to overwrite them. During the first installation, replace initrd.gz and vmlinuz without the same name. During the restart, install initrd.gz and vmlinuz on Ubuntu. If you are prompted to cancel the mounting, you must click to continue the installation, but the mouse and keyboard cannot be moved. Therefore, the Windows XP system is forced to shut down, and files of the same name are found under E:/Ubuntu/install/boot, overwritten again, and restarted. You can move the mouse this time and click to continue the installation. Everything goes well ~

Later, I deleted and reinstalled Ubuntu because it was messed up by me.

Deleting Ubuntu is exactly the same as deleting common software. Under XP (because I installed it in XP), go to control panel, add or delete software, find Ubuntu, and click Uninstall.

 

Windows XP multi-system Deletion

 

One day I suddenly found that I was unable to access the internet for the win7 flagship version 7100, so I planned to delete and reinstall it!

 

1. First format the hard disk of the win7 system.

 

At the beginning, the formatting was not successful. It was always said that there were files in use that could not be used. Some people in Baidu said that there was a permission problem. windows with a lower version could not format the hard disk of a Windows with a higher version. This is not the case. I first deleted all the software installed on drive D (in the XP system, my XP is on drive C, win7 is on drive D, and Ubuntu is on drive E), and then reinstalled on drive C. No. It cannot be restarted twice. Later, it was found that the donkey was installed on the d disk and started automatically when it started up. As a result, it said what the D disk was being used .. After exiting the donkey and uninstalling it, NTFS will be quickly formatted for a few seconds ..

 

2. Remove the win7 startup item in the next step.

 

Premise: You must have an ISO image for Windows 7, or a CD. It is not a single version.

Use deamon tools (Virtual optical drive) to load the ISO of win7 or put the CD in the optical drive, open the run or shortcut key win + R, Enter cmd and press enter, and then enter K in the Command Prompt window: /boot/bootsect.exe/nt52 all/force and press enter (k is the drive letter of your win7 iso or optical drive, D, E, F, and so on ). Then, pop up the ISO file or remove the CD file and restart it. At this time, we will find that early version windows or earlier versions of Windows are gone. If it was a dual system, we should directly enter the remaining system, and I will leave XP and ubuntu ~

This method to remove the win7 boot item also appliesRemove the startup Item of the window7 Installer.

Once I installed Windows 7 for my students and installed it when I needed to restart the system, I clicked restart. Every time the Windows icon on the welcome page appeared a little bit (not from small to large) the blue screen. Instead, you can choose not to install it first, but each time you start a Windows 7 installation program, the startup Item is there. Therefore, the above method was used to remove it successfully, and XP was directly entered every time (she is Lenovo y450, and only XP before Windows 7 is installed ).
